Combustion studies have shown that TKX-50 burns slightly faster than HMX and approaches the burning rate of CL-20. The combustion of TKX-50 has been shown to obey mechanism with the leading reaction in the condensed phase. The rates of TKX-50 decomposition in both solid and liquid phases proved to be slightly higher than the corresponding rates of decomposition of RDX. Decomposition of TKX-50 is determined by decomposition of free hydroxylamine formed in the reaction of dissociation of the salt. An intermediate decomposition product is ammonium salt of 5,5'-bis (2-hydroxytetrazole), which further decomposes in the second stage at elevated temperatures. The enthalpy of formation of TKX-50 has been measured with the help of bomb calorimetry, however the resulting value is quite different from the enthalpy reported earlier.","TRCRefID":{"yrYrPub":"2015","tml_elements":["yrYrPub","sAuthor1","sAuthor2","nAuthorn"],"nAuthorn":"0","sAuthor2":"fil","sAuthor1":"sin"},"sAuthor":["Sinditskii, V.
